I'm naive and didn't realize Amazon wouldn't ship internationally by default. I just updated the listing to enable international shipping which should take effect in a couple days. Thanks!
Congrats on the write up/production too. Looking forward to ordering one ASAP.
Oh, and thanks for the great work on the U2F device, and especially on open sourcing the whole thing. I'll probably order a couple to experiment with as well, as soon as they're available for shipping to Belgium :-)
